We’ve found that a Kailo with our adhesive backing can be removed and reapplied to your skin multiple times before losing its stick. When the adhesive loses its stick, wash it gently with soap and water to renew its stickiness. If that doesn’t work, simply peel the adhesive off and put on a new one. The adhesive backing is double-sided. One side, made of an acrylic-based adhesive is applied to the Kailo. The other side, made of a skin-friendly, silicon-based adhesive, should be applied to your skin. *A small percentage of customers have reported allergic reactions to our silicone-based adhesive Adhesives only, Kailo and Carry Case not included.
